Definitions
- This invention relates to apparatus, systems, and methods for connecting drive controls to motors and more particularly, although not necessarily exclusively, to devices providing mechanical and electrical connections between drive controllers and motors of pumps of water-circulation systems of swimming pools and spas.
- Multi-speed motors are configured to change rotational speed upon command. Such commands may originate with a computerized controller capable of transmitting the commands to a motor. Although transmission may occur wirelessly, often commands are transmitted via wire from controllers to motors.
- At least some controllers are configured to mount onto the motor housings. These controllers, then, require both mechanical connections to the housings and electrical connections to the internal motors. At least some controllers, further, are designed or rated for use with motors of particular output, so that some method of ensuring that a controller and motor are compatible prior to attempted operation would be beneficial.
- Standardization of the connectors across a line of pumps of a manufacturer likewise may be advantageous.
- alignment and keying of connectors may be intuitive and designed to reduce, if not minimize (or wholly prevent), errors in attaching drive controllers to motor housings.
- An installer may position a controller adjacent— and preferably above— a motor housing so that a tower of the housing aligns and fits snugly within a chimney-like opening of the controller.
- a keying pin of the controller aligns with a mating hole of the motor housing.
- Continued lowering of the controller causes male electrical terminals of the controller to fit into female terminals of the motor housing configured to convey electricity to the motor inside the housing. Proceeding in this manner results in mechanically and electrically connecting the drive controller to the motor housing while protecting the male terminals from
- the present invention may include its modular nature and capability of providing complete sealing between the printed circuit boards (PCBs) and housings of the drive controllers so that drive electronics can be encapsulated without leaking or contaminating the electrical terminals. Accordingly, the present invention may provide robust mechanical guidance and alignment, solid electrical connections, and inherent keying of drive controllers and motor housings.
- PCBs printed circuit boards
- FIGS. 1-2 are views of a drive controller illustrating aspects of an exemplary keying system of the present invention.
- FIGS. 3-4 are views of a motor housing illustrating aspects of the exemplary keying system of FIGS. 1-2.
- FIG. 5 is a cross-sectional view of an exemplary connector design similar to the keying system of FIGS. 1-4.
- FIGS. 1-2 depict a (nominally lower) portion 10 of a drive controller including aspects of the present invention. Illustrated in FIGS. 1-2 is chimney 14, which as shown is recessed into the housing of the controller. Also shown in FIGS. 1-2 protruding outward from a base of the chimney 14 are male terminals 18. Terminals 18 may, but need not necessarily, be part of an interface PCB that mounts within chimney 14. Although four such terminals 18 are depicted, more or fewer terminals 18 may be used instead. In general, the walls of chimney 14 function to provide substantial protection for the terminals 18.
- pin 22 protrudes outward from portion 10 adjacent chimney 14 and is of generally cylindrical shape. Pin 22 need not be positioned or shaped or sized as shown in FIGS. 1-2, however, depending on the structure to which it is to be keyed.
- First gasket 26 further is illustrated in FIGS. 1-2.
- Gasket 26 may provide a seal between the PCB containing terminals 18 and the walls or upper lip 28 of chimney 14. Gasket 26 additionally may provide mechanical support (strain relief) to terminals 18.
- FIGS. 3-4 depict a (nominally upper) portion 30 of a motor housing including aspects of the present invention. Further depicted is motor connector tower 34, which may be secured to portion 30 and hold terminal block 38. Block 38 may contain female terminals 42 (preferably of the“FastOn”-type), four of which are shown.
- Tower 34 moreover, may include mating hole 46, which as shown constitutes a generally cylindrical recess positioned adjacent a tower wall.
- Tower 34 is configured to fit snugly within chimney 14, thereby supplying initial alignment of the controller and motor housing before pin 22 reaches hole 46.
- pin 22 is sized, shaped, and positioned ( i. e . keyed) so as to be received into hole 46, further tightening of the alignment may occur. These alignments facilitate mating of male terminals 18 and female terminals 42, hence reducing the possibility of the terminals being damaged by any misalignments that otherwise might exist.
- pin 22 may protrude sufficiently so that it engages hole 46 prior to contact between tower 34 and chimney 14, although this alternative approach presently is not preferred.
- Supplemental gaskets may, if desired, be used.
- a second gasket for example, may be placed at the base of tower 34 and function to seal space between tower 34 and chimney 14 to reduce ingress of debris and moisture into the space.
- a third gasket may be positioned under tower 34 to prevent ingress of debris and moisture into the motor within the motor housing.
- FIG. 5 provides a cross-sectional view of an exemplary connector design consistent with the present invention and similar to that of FIGS. 1-4.
- the figure is labelled to identify various components and features of the design.
- the foregoing is provided for purposes of illustrating, explaining, and describing embodiments of the present invention. Modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of the invention. Additionally, the word“pool” and phrase “swimming pool” as used herein may include vessels such as spas and hot tubs within its definition.
